Staining and resin embedding of whole Daphnia magna samples for micro-CT imaging enabling 3D visualization of cells, tissues, and organs.

Micro-CT imaging is a powerful tool for generating high-resolution, isotropic, three-dimensional datasets of whole, centimeter-scale model organisms. At histological resolutions, micro-CT can be used for whole-animal qualitative and quantitative characterization of tissue and organismal structure in health and disease. The small size, global freshwater distribution, wide range of cell size and structures of micron scale, and common use of Daphnia magna in toxicological and environmental studies make it an ideal model for demonstrating the potential power of micro-CT-enabled whole-organism phenotyping.

Weekend Headaches in School-Age Children.

Children commonly encounter primary headaches, with various factors playing a role in their onset. The daily routine notably contributes to the occurrence of primary headaches in children. This study aims to profile children experiencing headaches on weekends (WH) in comparison to those primarily having headaches midweek (MWH).

Absence of Spontaneous Magnetic Fields due to Time-Reversal Symmetry Breaking in Bulk Superconducting UTe_{2}.

We have investigated the low-temperature local magnetic properties in the bulk of molten salt-flux (MSF)-grown single crystals of the candidate odd-parity superconductor UTe_{2} by zero-field muon spin relaxation (μSR). In contrast to previous μSR studies of UTe_{2} single crystals grown by a chemical vapor transport method, we find no evidence of magnetic clusters or electronic moments fluctuating slow enough to cause a discernible relaxation of the zero-field μSR asymmetry spectrum. Consequently, our measurements on MSF-grown single crystals rule out the generation of spontaneous magnetic fields in the bulk that would occur near impurities or lattice defects if the superconducting state of UTe_{2} breaks time-reversal symmetry.

[Cardiac rehabilitation: investigation of efficacy, results, perspectives].

Previous research experience on cardiac rehabilitation programs as a part of general health care system has shown that they are an important part of the management of cardiovascular patients. Improving quality of life, reducing the severity of risk factors, increasing physical performance, slowing disease progression, decrease in morbidity and mortality indicate the clinical efficacy of cardiac rehabilitation and make it an integral part of therapeutic interventions. Heart rehabilitation is a 1st class recommendation in the majority of modern cardiovascular guidelines around the world.

[Noninvasive peripheral magnetic stimulation in the treatment of neurogenic urination disorders in children].

Unlabelled: Neurogenic urination disorders in children are often clinically represented by urinary incontinence (UI). The prevalence of UI reaches 8.6%, but tends to decrease in frequency with age.
